culinary machines, and more particularly to a machine designed for a great many uses in the kitchen in the preparation of foods, such as mashing potatoes, straining soup, kneading dough, strainingfruits, and

berries for jellies, beating-eggsand for a great many other uses, the object of theinvention being to construct an improved machine ofthis character; with an improved ellipsoidal receptacle, in which whips or heaters are rapidly rotated to throw the materials outwardly and upwardly, by means of a motor, and as will be more fully hereinafter pointed'out. a \Vith this and other objects in view, the 'invention consists. in certain novel features of construction, combination and arrangement of parts as will be more fully hereinafter described and pointed out in the. claims.

In the accompanying drawings, Figure 1 is a side elevation of a machine illustrating my improvements; Fig. *2, is a sectional elevation of the same; Fig. 3, is a fragmentary view in section, showing the soup strainer and whip in position; Fig. 4, is a view similartoFig. 3, showing the dough kneader or whip in position; Fig. 5, is a plan view of. the device with the cover removed, showing the potato mashing whip in position; Fig. 6, is a view similar to Fig. 5, showing the soup strainer andwhi'p in position; Fig. 7, is an inverted plan View of the cover; Fig. 8, is an enlarged frag-' mentary view showing the cover locking device; Figs. 9, 10 and 11, are perspective- ,views of the different, whips, and Fig. 12,

is a perspective View of the strainer.

1 represents a hollow base, having a'ne'x-- tension 2 at its upper end, form-ing a" table 'or platform. Aseries'ofcurved uprights 3 are secured-to the top of base 1 by means of bolts 4, and these uprights are recessed at their upper ends at opposite sides to form shoulders 5 and tongues 6, and when the latter are positioned in the grooved blocks 7, preferably integral with the receptacle 8, such shoulders will limit the downward movement of the receptacle and position the latter in operative relation toan electric motor 9, located in the base 1. The motor 9 is preferably mounted in a bracket 10', secured by bolts 11 to a cross bar 12, said cross bar 12 being secured by-screws or bolts 13 to lugs 14 in the base.

The receptacle 8 with its cover 15, form an inclosure Qf' general ellipsoid 1 Shape, which together with the forms if whips employed, impart a-distinctadvantage to the 4 culinary operations carried on in such inclosure as Will be more, fully set forth. The cover 15 is provided with a. series of i -shapcd lugs 16, to engage lugs or pins 17 on the receptacle 8, the parts forming, in effect, bayonet joints and securely locking is placed on the receptacle, it is given a partial turn until its lug 16 engages under the lugs 17 of the receptacle to effect locking of the same thereto. This receptacle 8 is provided at its lower end, with a depending. tubular extension 18, and an upwardly projecting tube 19 is externally screw '18 and tube 19 are adapted to receive the ordinary motor shaft 20, which latter is made angular near its upper end as shown at 21, and is screw threaded above the angular portion as shown at 22 for the reception of a thumb nut 23 to lock-the dilferent whips on the shaft.

Figs. 2 and 9 illustrate a potato mashing whip 2a, and while I shall refer to this whip, as the -potato mashing whip, it is to be understood that it is designed for a great many uses, such as heating eggs, whipping cream, etc, and I do. not confine myself to any particular use for this whip. This whip 2-4 comprises a central cylindrical bearing sleeve 25, having integral radial vanes 26, which are diagonally slotted as shown, providing a series .of inclined spokes 27, the latthe cover to the receptacle. Vhen the cover ter being preferably-beveled or flattened as illustrated. The upper end of the bearing sleeve 25 is provided with a restricted rectangular opening 28, to snugly fit the angular portion 21 of the motor shaft, and when the thumb nut 23 is screwed home, tightly clamping the whip on the shaft, the motion 'of the shaft will be transmitted to the whip,

as will be readily understood.

hen the whip is in operation, the potatoes or other material within the receptacle will be thrown outwardly and upwardly by reason of the shape of the receptacles, and will fall back into center of the receptacle to be again thrown outwardly and upwardly, until the operation is completed. This operation is the reverse of that of ordinary machines, which exert a downward pressure upon the material, and obviates any tendency to compact the materials in the bottom of the receptacle, but insures a light fluffy-product.

' The receptacle 8 is provided with a discharge opening 29, normally closed by a screw plug 30; suchopening beifig preferably above the table, so that the contents of the receptacle-may be directed into a pan (not shown) on the platform whenever the plug 30 is removed, which will be the case in straining soup. On the inner face of receptacle 8 near its lower end, a circular groove 31 is provided, forming 'a seat or .ledge, to receive a perforated plate or strainer 32, which latter is provided with a central sleeve 33, to accommodate the lower end of the central bearingsleeve'34 of the strainer whip 35. This strainer 32 is provided in its edge with a notch 36, adapted to engage over a.

pin or lug 37 'in the grooved portion 31 of the receptacle 8, tolock the strainer against rotary movement. The whip 35 has two open'wings or plates of the shape shown in Fig. 10, the lower portion of said plates being horizontal and flat, as at 38, to rub against the strainer, and to free the erforations in the latter of all accumulated material. While this strainer is particularly adapted. to straining soup, it is also adapted for straining a great many other fruifistufi's, and I am, of course, not limited in its use.

Fig. 11 illustrates in. detail, a dough kneader or whip, comprising a disk 39, having an angular opening therein to receive the angular portion 21 of the motor shaft,

and provided with two curved rods or wires 40, having the peculiar compound curvature shown, giving to'the lower ends of the rods or wires, what constitutes in effect, fingers 41 which, when the whip is revolved, pick up particles or balls of dough and roll the same against the sides of the receptacle, and upwardly in the receptacle. As the dough will fall back toward the center of the receptacle,

the operation is constantly repeated to thoroughly knead the dough.

It will thus be observed, that with my improved machine, all of the whips exert upon the material in the receptacle an outward and upwardly throwing action, which owing to the ellipsoidal shape, of the receptacle insures the materials falling back to the center to receive again the same movement, and this operation is continued as long as the whip is revolved by the motor. The whips can be readily changed by simply removing the thumb nut 23, and the whole apparatus can be readily cleansed and maintained sweet and clean 'without difliculty.

The device may be ornamented in any desired manner, and an ornamental handle 42 is preferably secured to the cover 15 by means of screw 43. i

Various slight changes might be made in the general form and arrangements of parts mounted-and held against rotary movement,

a drive shaft projecting upwardly through the receptacle from said base, a tubular member fixed to said receptacle and surrounding said shaft, a whip disposed within the receptacle and removably mounted on said shaft, and a tubular extension depending from said receptacle and entering the aperture in the platform, said extension serving to center and stay the receptacle.
